Two New Cynodonts (Therapsida) from the Middle-Early Late Triassic of Brazil and Comments on South American Probainognathians. [PDF]
PLoS ONE, 2016 We describe two new cynodonts from the early Late Triassic of southern Brazil. One taxon, Bonacynodon schultzi gen. et sp. nov., comes from the lower Carnian Dinodontosaurus AZ, being correlated with the faunal association at the upper half of the lower ...

DICYNODONT JAW MECHANISMS RECONSIDERED: THE KANNEMEYERIA (ANOMODONTIA THERAPSIDA) MASTICATORY CYCLE
Publicación Electrónica de la Asociación Paleontológica Argentina, 2015 The unique feature of the dicynodont masticatory apparatus is the double-convex jaw articulation, which permitted free antero-posterior movement. Since Crompton and Hotton's demonstration of the jaw articulation, most subsequent work has argued either ...

New whaitsioids (Therapsida: Therocephalia) from the Teekloof Formation of South Africa and therocephalian diversity during the end-Guadalupian extinction [PDF]
PeerJ, 2017 Two new species of therocephalian therapsids are described from the upper Permian Teekloof Formation of the Karoo Basin, South Africa. They include two specimens of a whaitsiid, Microwhaitsia mendrezi gen. et sp.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning. [PDF]
Anat Rec (Hoboken)Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Palaeoneurology and palaeobiology of the dinocephalian therapsid Anteosaurus magnificus [PDF]
Acta Palaeontologica Polonica, 2021 Dinocephalians (Therapsida), some of the earliest amniotes to have evolved large body size, include the carnivorous Anteosauria and mostly herbivorous Tapinocephalia. Whilst the palaeoneurology of the Tapinocephalia has been investigated in Moschognathus

Whole-body endothermy: ancient, homologous and widespread among the ancestors of mammals, birds and crocodylians. [PDF]
Biol Rev Camb Philos Soc, 2022 ABSTRACT The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long held to have evolved independently in each group, a reasonable assumption when it was believed that its earliest appearances in birds and mammals arose many millions of years apart.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage. [PDF]
Anat Rec (Hoboken)Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.
